I need to ask another qustion? I need to convert the same type of textbox data
to money. I think I can use the same concept you gave me but what would the
the format look like? I tried this: "String.Format("${(0).}", Convert.ToInt32(s))". There is a format error at runtime.

Have a look here[^] for all your string formatting questions Norm. I think this will solve your problems.
Hope this helps.

In Photoshop CS there is such functionality:
Image>Adjustments>Threshold
I do need to implement such functionality in my c# application, but I don't know how!? Does any of you know where I can find such implementation?
Thanks in advance

you can try this www.mathtools.net you may find various image processing algorithms written either in c++ or matlab... Alternatively, GOOGLE. Or go read the book from John C Russ, you may find a pseudo algorithm in his book.
edit: you can try the mathworks website and go to the user decidated code section and browse through the image processing section. There is a tonne of image processing code written in matlab.

Try this peace of code .. instead of giving an error it connects to a ipHostEntry that doesn't exist
Can anyone tell me why ?
Why me ? Oh .. why ?
using System;
using System.Net;
using System.Net.Sockets;
namespace ThisIsStupid
{
public class MainC
{
public static void Main()
{
IPEndPoint ipe = new IPEndPoint( IPAddress.Parse( "193.168.0.6"),21);
//System.Diagnostics.Debug.WriteLine( ipadd );
Socket s = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
// Console.WriteLine(s.Connected );
s.Connect(ipe );
if( s.Connected )
{
Console.WriteLine( " I have a socket that didn't connect to nothing ");
Console.WriteLine(" But it's status is connected ");
Console.WriteLine(" Uraaa !");
}
}
}
}

I extended your class so I could see what was happening. When I tried the other ports you mentioned I got an exception to say that it wasn't connected. When I tried port 21 my application returned:

I am getting errors when I try to insert data into my database. I dont have any problems viewing the database. I think it is a problem with my insert statement:
oleDbInsertCommand1.CommandText="INSERT INTO UserTable(Username,Password) VALUES('@NewUserTextBox.Text','@NewPasswordTextBox.Text')";
oleDbInsertCommand1.ExecuteNonQuery();
I have even tried it without the @ and other ways. This is the error I get below.
System.Data.OleDb.OleDbException: Syntax error in INSERT INTO statement.
at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(Int32 hr)
at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams, Object& executeResult)
at System.Data.OleDb.OleDbCommand.ExecuteCommandText(Object& executeResult)
at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult)
at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method)
at System.Data.OleDb.OleDbCommand.ExecuteNonQuery()

You can do it this way, but it's susceptible to SQL injection attacks (a common way that malicious users can attack a web site and destroy databases):
oleDbInsertCommand1.CommandText="INSERT INTO UserTable(Username,Password) VALUES('" + NewUserTextBox.Text + "','" + NewPasswordTextBox.Text + "')";
Instead you should set up an oleDbParameter collection and attach it to the oleDBInsertCommand1 object. You'd populate the paramters from the two textboxes (NewUserTextBox and NewPasswordTextBox). If you named these parameters '@NewUser' and '@NewPassword' respectively, then you'd code the CommandText as follows (notice that there are no single quotes here):
oleDbInsertCommand1.CommandText="INSERT INTO UserTable(Username,Password) VALUES(@NewUser, @NewPassword)";
This is the secure, recommended best-practice solution. There is more help on parameter collections in the Visual Studio on-line help.

I need to know how to re-draw graphics on my forms when the forms are minimized or lose focus. I know there are an Update() and Invalidate() method but when I use them they don't work. I need to know where to put them actually.
I already know that the OnPaint() method is called when the form loses focus and graphics need to be drawn. The reason i don't want to go that route is because I am using a button control that when pressed, there are counters that will change the coordinates of the graphic shape. This means I would have to save the current state or coordinates after each time the button is pressed and it would be a hassle to pass all of this to the OnPaint() method, even though it could be done.
I just need a simple way to redraw my graphics in the forms.
|
|
|
|
|
save all the graphics in an ArrayList
make some class like Elipse , Arc.. etc
OnPaint()
foreach ( drawing in myDrawings )
{
drawing.Draw( e.Grahics ) ;
}

I have a program that includes 2 splash screens. They both load correctly but the one that has a flash movie in it will just load and not play the movie. I think it is because I am using a Thread.Sleep(), that will just load the form but not execute any functions. If I load the flash form without threading the movie will play, so I know it is not an playback issue. This is a sample of the code in the Main() function.
LogoSplash logo=new LogoSplash(); //This works good
logo.Show();
Application.DoEvents();
Thread.Sleep(5000);
logo.Close();
FlashSplash flash=new SplashScreen(); //This is where i have issues
flash.Show();
Application.DoEvents();
Thread.Sleep(10000); //will execute, but not play movie
flash.Close();
Application.Run(new ParentForm());
I just want the flash splash form to load and play for 10 seconds, terminate and then load the main form.
If there is another route please, can anyone lead me in that direction.

You coud try not putting the thread to sleep .. and use a timer inside the flash splash screen..
and maybe do something like
Application.Run( new SpashScreen() );
// when the 10 seconds are up
inside the tick counter .. this.Close();
then the ParentForm() is going to appear ...
